  • Patent number: 7491768
    Abstract: The present invention relates to an anti-microbial or anti-coagulating polymer resin and a method for preparing the same, and a medical appliance or instrument using the same, and more particularly to a method for preparing an anti-microbial or anti-coagulating medical polymer resin comprising the steps of simply mixing a polymer resin with at least one kind of pharmaceutically active material without using a solvent. The pharmaceutically active material is preferably an anti-microbial or anti-coagulant. According to the present invention, an anti-microbial or anti-coagulating material that is safe to a human body is mixed with a polymer resin by simple addition in an environmentally favorable non-solvent method, thereby maintaining superior anti-microbial effects even after high temperature molding, minimizing a released amount of anti-microbial to increase anti-microbial effect durability, and solving a toxic problem in a body.

  • Patent number: 6900262
    Abstract: The present invention generally provides a method for producing an exfoliated nanocomposite. The method involves charging to water, as the continuous phase, monomers, polymerizable surfactant, and water-soluble initiator. The monomers are allowed to polymerize under agitation to form an emulsion of polymers, and the polymerizable surfactant is bound to the polymers so formed, with an ionic end of the polymerizable surfactant extending from the polymers to provide surface charges. Thereafter, a suspension of nanofillers in water is charged to the emulsion. The nanofillers are oppositely charged from the ionic end of the polymerizable surfactant such that they electrostatically bind to the polymers within the emulsion. The water is subsequently decanted to produce a nanocomposite with an exfoliated structure.

  • Patent number: 6887925
    Abstract: A molding material for use with carbon dioxide, which comprises chlorinated polyethylene having a chlorine content of 25-47% by weight or a blend of chlorinated polyethylene with vinyl chloride-based resin, can be used as a suitable material for sealing materials in carbon dioxide-contacting apparatuses using carbon dioxide as a refrigerant. Addition of a specific silane coupling agent to the molding material can effectively prevent vulcanization moldings from blister generation.

  • Patent number: 6881781
    Abstract: A non-toxic malleable, bounceable modeling compound stretchable in a manner similar to chewing gum which is particularly suitable for children. The compound is comprised essentially of a butyl rubber, vulcanized vegetable oil, one or more softening agents, an inorganic filler material, antioxidant and binder. The pliable compound can retain a molded shape for years and is an ideal sculpting material, stress reliever, and aid for improving dexterity. The compound is produced according to a tri-phase process that does not require heating or baking.

  • Patent number: 6878310
    Abstract: A stabilizer composition, suitable for use in polyvinyl chloride compositions, can be formed by reacting a mixture of monoalkyltin trichloride, such as butyltin trichloride, and dialkyltin dichloride, such as dibutyltin dichloride, with at least one carboxylic acid, such as 2-ethylhexanoic acid, and 2-mercaptoethanol, in the presence of base, followed by reaction of the resulting product with a sulfide reagent, such as sodium sulfide. The final composition comprises a complex mixture of alkyl tin carboxylates and/or mercaptides, and of monoalkyltin sulfides and dialkyltin sulfides.

  • Patent number: 6872854
    Abstract: Metal salts of organic acids complexed with ?-diketone compounds are multifunctional complexes useful in the formulation of stabilizers for halogenated resins. These complexes may be used jointly with other low toxicity intermediates, such as zinc or magnesium intermediates, to form effective stabilizers that are non-toxic and exhibit better performance than other known stabilizers, including those containing toxic heavy metals such as cadmium or lead. The complex is prepared utilizing a Claisen condensation reaction and precipitation with water and heptane.

  • Patent number: 6852791
    Abstract: An anti-reflection coating-forming composition is provided. This composition includes a polymer and a solvent. The polymer has a structural unit represented by the formula (1): wherein R1 is a monovalent atom other than a hydrogen atom or a monovalent group, and n is an integer of 0-4, provided that when n is an integer of 2-4, a plural number of R1's are the same or different; R2 and R3 are each a monovalent atom or group; and X is a bivalent group. The anti-reflection coating formed from this composition has a high antireflective effect, does not generate intermixing with a resist film, and enables a good resist pattern profile excellent in resolution and precision in cooperation with a positive or negative resist.
